Yuuka Ichinose, a newly hired saleswoman, faces severe consequences when her careless and flippant attitude pushes a construction company president to his limit, triggering brutal disciplinary action. The assault begins with humiliating forced milk enemas, followed by deep-throat induced massive ejaculations, and setting a new Guinness record by impaling ten cotton swabs into her anus. She endures extreme torment including kicks, slaps, and simultaneous penetration of both her anal and vaginal openings. The punishment culminates in a fist being driven into her anus—delivering literal iron-fist discipline. Finally, she is urinated into her anus and forced to perform a vomit-filled deep-throat act, completing a hellish initiation ordeal.
